Scientists in Australia have demonstrated a new way to apply a passivating contact layer to silicon cells. They produced an n-type cell with aluminum-titanium passivating contact and 21.9% efficiency, and claimed the technique could open up new possibilities for the use of transition metal oxides in cell passivation.As single-junction silicon solar cells push closer to their practical efficiency limit (somewhere around the 30% mark), it becomes more and more difficult to find further improvements to performance. And while plenty of PV research is already looking to multijunction devices and other ...Den vollständigen Artikel lesen ...
